Winnie-the-Pooh, also called Pooh Bear and Pooh, is a fictional anthropomorphic teddy bear created by English author A. A. Milne and English illustrator E. H. Shepard.

The first collection of stories about the character was the book Winnie-the-Pooh (1926), and this was followed by The House at Pooh Corner (1928). Milne also included a poem about the bear in the children's verse book When We Were Very Young (1924) and many more in Now We Are Six (1927). All four volumes were illustrated by E. H. Shepard.

The Pooh stories have been translated into many languages, including Alexander Lenard's Latin translation, Winnie ille Pu, which was first published in 1958, and, in 1960, became the only Latin book ever to have been featured on The New York Times Best Seller list.

In 1961, Walt Disney Productions licensed certain film and other rights of Milne's Winnie-the-Pooh stories from the estate of A. A. Milne and the licensing agent Stephen Slesinger, Inc., and adapted the Pooh stories, using the unhyphenated name "Winnie the Pooh", into a series of features that would eventually become one of its most successful franchises.

In popular film adaptations, Pooh has been voiced by actors Sterling Holloway, Hal Smith and Jim Cummings in English, and Yevgeny Leonov in Russian.
